母婴血型不合导致新生儿溶血病的实验室诊断技术分析

目的：探讨临床母婴血型不合引发新生儿溶血病（HDN）的血型分布，分析其诊断技术对临床的价值。方法选取本院2014年4月～2015年4月送检的420例疑似HDN患儿血液样本作为研究对象，对其进行ABO和Rh血型鉴定，检测其直接抗人球蛋白、游离液抗体及放散液抗体的水平。结果采用血型的血清学检测检测出由于血型不合而引发新生儿溶血病的有242例，阳性率为57.6%，其中ABO-HDN的有240例（57.1%），而Rh-HDN的有2例（0.47%）。在71例O型血患儿中，采用直接抗球蛋白和不规则抗体检测时均为阴性。已证实为ABO-HDN的240例患儿中，A型的为104例（43.3%）， B型的为136例（56.7%）。结论本次研究的由于血型不合而导致新生儿溶血病中，ABO-HDN较为常见，而其中以母亲为O型血的B型血新生儿较多见。通过对新生儿溶血病的血型相符度进行检测，对新生儿溶血病的诊断及治疗具有重要的临床意义。     

护理心理学实验室建设与实验教学

护理心理学是护理学和心理学相交叉而产生的一门新兴边缘学科，是高等护理教育中一门重要的课程。护理心理学有助于培养护理人员的整体护理观念，为病人提供身心整体护理，从而提高护理质量。护理心理学实验教学作为护理心理学教学中的重要环节，对于帮助学生巩固和理解所学理论知识，培养学生的科学态度、实践能力和创新意识具有重要意义。护理心理学实验室的建设是保证实验教学质量的重要条件。我院护理心理学实验室经过10多年的发展，已建设成为针对护理专业学生的，设备齐全与管理完善的开放实验室。现从硬件建设、软件建设、管理体系以及实验教学改革情况等方面进行介绍。     

Outcome prediction for Bonebridge candidates based on audiological indication criteria

ObjectiveTo re-evaluate current indication criteria and to estimate the audiological outcomes of patients with Bonebridge bone conduction implants based on preoperative bone conduction thresholds.MethodsWe assessed the outcome of 28 subjects with either conductive or mixed hearing loss (CMHL) or single-sided deafness (SSD) who were undergoing a Bonebridge implantation. We used linear regression to evaluate the influence of preoperative bone conduction thresholds of the better/poorer ear, indication group, and language (German- and French-speaking patients) on aided sound field thresholds. In addition, aided word recognition scores at 65 dB sound pressure level were fit with a logistic model that included preoperative bone conduction thresholds of the better/poorer ear, indication group, and language as effects.ResultsWe found that both aided sound field thresholds and word recognition were correlated with the preoperative bone conduction thresholds of the better hearing ear. No correlation between audiological outcomes and the preoperative bone conduction thresholds of the poorer ear, language, or indication group was found.ConclusionBone conduction thresholds of the better hearing ear should be used to estimate the outcome of patients undergoing Bonebridge implantation. We suggest the indication criteria for Bonebridge candidates considering maximal bone conduction thresholds of the better ear at 38 dB HL to achieve an aided sound field threshold of at least 30 dB hearing level and an aided word recognition score of at least 75% for monosyllabic words.

Comments on: Perioperative von Willebrand factor dynamics are associated with liver regeneration and predict outcome after liver resection

正Recentlythearticle"PerioperativevonWillebrandfactordynamics are associated with liver regeneration and predict outcome afterliver resection" was published in Hepatology[1].Prof.Starlinger et al. aimed to assess the association of von Willebrand factor (vWF) levels and clinical outcome in patients with liver cancers post-liverresection(LR).Basedonthemechanismthatplatelets accumulation in the liver may promote liver regeneration after partial LR in mice, they found the vWF-dependent pattern of platelets accumulationduringliverregenerationinpatientsaftersurgery.     

Converging global crises are forcing the rapid adoption of disruptive changes in drug discovery

Spiralling research costs combined with urgent pressures from the Coronavirus 2019 (COVID-19) pandemic and the consequences of climate disruption are forcing changes in drug discovery. Increasing the predictive power of in vitro human assays and using them earlier in discovery would refocus resources on more successful research strategies and reduce animal studies. Increasing laboratory automation enables effective social distancing for researchers, while allowing integrated data capture from remote laboratory networks. Such disruptive changes would not only enable more cost-effective drug discovery, but could also reduce the overall carbon footprint of discovering new drugs.
